One Step Closer
@ 07:05 pm (GMT) |
Paul LevermanJust ordered a Jewell (HVR) from RPS International. Should be here within the week. Once it gets here, I can finish the inletting and bedding. Brass is all ready to go. Finally found some TrailBoss for fireforming.[/img]https://picasaweb.google.com/100751113000647702088/6307258024597989521[/img] |

Paul LevermanRe: One Step CloserGood eye, Jason. Proportionately speaking, it is almost identical to a 6PPC, with a few minor variances. It's as close as I could get and stay within reason.It started life as a 577NE-3-1/4", got cut down to a 585 Nyati, and then morphed into a .338SPL. |

jasonRe: One Step CloserI see.I only had a bit of an idea as iv just started a br project. .22 It looks and sounds like a lot of work. |

Warwick MarflittRe: One Step CloserIt's a Pygmy Sumo cartridge Paul! |

Paul LevermanRe: One Step CloserNot sure if you can see it in the photo, but there is a bright ring on the neck. This is the false shoulder for fireforming. When formed, the shoulder will be blown forward to that point, increasing case volume. As it sits now, case capacity to the shoulder/neck junction is 87gr. of 7828. Overall length of brass is 2.081" (52.8mm). |

Thomas KitchenRe: One Step Closergood to see your still plugging away with your project Paul.it look interesting alright. is this the P14 project? i got the other trigger sitting here to go in my P14 when i find sometime but every time i see it i wonder how you are getting on with your one. |

Paul LevermanRe: One Step CloserHi Thomas - this is project #1, the P-14 is #3. Still waiting to get the P-14 back from being chambered. Thanks to you, for suggesting the Timney for it. What a great trigger! Clean and crisp, easily adjusted. Everything you want in a trigger. And, it was in the Canada, so no hassles at the border. BIG BONUS!The trigger for #1 was shipped on Friday last, so should be here sometime around Wednesday/Thursday I'm hoping. Again, it was in the country, next province east of here, so pretty well local. Can you still see the photo above? When I log in, it doesn't show up. It doesn't say the link is broken, so maybe it's just me. Nice .35 you built. Love the way that barrel looks on it. |

Thomas KitchenRe: One Step Closerhi Paul.i could see the picture on my phone but not my computer just thought it was my computer it might pay to post it again. should i even ask what project #2 is? lol you might have to run us through what project #1 is and on what action etc if you haven't already. that 35/303 came up real nice Grant at trueflite really knows his stuff, the barrel looks solid and short but because of the big hole down the middle its nice and light, the balance point is just in front of the magazine which is perfect for carrying |

Paul LevermanRe: One Step CloserA long time ago, in a galaxy far, far.........oh, wait, they already used that one. But in this case, it is entirely appropriate. I've been on and off this cartridge for so long, I really don't remember when I first got the idea or started working on it. I know it wasn't that far into Y2K, or there abouts. A long time ago. But parts availability, acceptable components, reliable sources and gunsmiths all took their toll on it. Basically, life in general kicked it to the back burner several times over. Without going into the failings encountered at just about every turn, this is where it stands today: |

Paul LevermanRe: One Step CloserWell, that didn't work.https://photos.google.com/share/AF1QipNaMqZwsXto2K8_1A6tAw28e18SOvwP8UXxD4rzZ7fMGxDDN3Mp3YfhASQv7w0FRg?key=cUpVNlE0eHFkQm5CcktnMDBkamJDaUt1RlZQbHhn Try this. |

Paul LevermanRe: One Step CloserThat's better.I don't remember how many different ways were tried to reduce that neck diameter, but it ended up where it was supposed to be. The shoulder is way low so I had room to work the bushings against the neck length I was looking for, and it will blow forward with enough boom behind it. The whole basis of this was to form a case that was proportionately identical to the 6PPC. And within reason, this one turned out. Oh, and it had to house a .338 bullet. What's ironic is that the reamer/cartridge/bullet/freebore relationship was all worked out for the longest, highest BC bullet of the day. Unfortunately, that is now defunct and the new bullets are waaaaay longer. But, sometimes luck works for you, and this was the case with the shoulder length. The original goal was to hold 85gr of H870, so the length was set to that. But when the squeezing and squishing was all said and done, I missed that length, was way to far forward, but it was too far gone to go back and correct it. Now with the new bullets (ie. the 285gr A-Max/ELD) the shoulder length I ended up with works perfect. More powder, probably more pain, but I can live with that if I can shoot 285's. Next step is to get the trigger (Jewell HVR) mounted to the action (Barnard PL) and finish inletting the stock (I will not ever name the manufacturer of this stock, as they are completely unmindful of customer service, are arrogant, and consider themselves some sort of demi-gods of the shooting world, which is the furthest thing from the truth. So there, you bush league family of wannabe shootists, put that in your corncob pipe and smoke it.), and bed it to perfection, I hope. It comes with a 31" straight taper SS Gaillard barrel out of Saskatchewan, topped with 36X Leupold AO piece of glass, mounted in Burris Posi-Zee Signature rings. It weighs in at roughly 17 pounds. Not your average elk rifle, but if it shoots well, it will be. |

Paul LevermanRe: One Step CloserI put the whole photo sequence into the "Test" forum if you want to see the step by step necking. Not sure if it will run as a slide show. |

Thomas KitchenRe: One Step Closerill see if this works Paul
so from my understand you start with a 577 NE trim the rim off it then remove the taper so it has a neck to head space on this give you the 585 nyati. from there you have neck that down to 338? and slowly shortened the case? im guessing you started with nyati brass thou. i was doing a bit of research and it looks like its same rim diameter as a 505 gibbs which the parent case for the cheytec rounds. i think the nyati steps out in front of the rim thou? looks like a lot of fun. |

Paul LevermanRe: One Step CloserThe 577NE is the parent case for the Nyati. I wasn't able to find formed Nyati cases, so I just bought the 577 straight walled cases. The first step was to lop off a bunch of the 577 length to get it closer to the finished size. This saved having to size an excessive amount of unwanted neck length. From there it was a progression of sizing down to finished size.The 505 Gibbs has a base diameter of .635", while this one is .660", about .024" bigger than a 28ga. shotgun shell. Not much difference in diameter, but huge difference in volume. Not sure if you could call it fun. It was a good lesson in patience and humility. It was definitely a labour of love, as no sane person would do this for no reason. I just finished all the pre-fireforming dimensional changes. Still waiting for the trigger hanger. Can't start the bedding process until I get the trigger mounted so I know where the hole goes through the stock. And I found out tonight, I have to rebuild the bullet seater. Too much clearance and too short. |

Paul LevermanRe: One Step CloserThe rifle and ammunition are ready to fire. Heading to the range. |

Paul LevermanRe: One Step CloserWell that was a good way to ruing a nice day. Apparently, it is no where near ready. After sizing, trimming, reaming and chambering each round individually, when loaded only two would chamber. It is probably a good thing that I was the only one at the range. |

Nathan FosterRe: One Step CloserDid bullet seating collapse the shoulder and push the body out a bit? It can happen sometimes. |

Warwick MarflittRe: One Step CloserThe Alley Cat don't want to play nice? It was always going to scratch and claw at you Paul! With hateful eyes and spiteful howls...... You'll need thick gloves to stuff it into its cage and calm it down with some carefully measured test and investigations. I hope it hasn't got Rabies!!!! Here the Wild cats get fixed with a spade.... Keep at it Mate as its a wicked looking thing! Be safe... |
